I am an 8 1/2. I have sent for a size 9 since there are not any half-sizes. Is there anyone else out there who has a half shoe size and bought a 1/2 size up?
It is usually a good idea to buy a half size up. Sanuk has a true fit so I feel going a half size down will make this product too small.
I would buy a half size down. I wear a 9.5/10, and I bought a 9 in this style. They are tight-ish for the first few hours, but they stretch a LOT. If I had purchased a 10, I'd never be able to wear them, because they'd be falling off of my feet with every step.
